NASA’s Mars Odyssey spacecraft has reportedly detected water ice under the surface of the red planet, according to scientific papers to be published this week, a finding that could be a giant step in exploration of Mars. Many astronomers believe Mars used to have quantities of liquid water on its surface, but they have never agreed on where the water went. Research to be published in this week’s edition of the journal Science may help answer that question.
